Thank you so much for your reply. Tylenol with codeine I believe is the same as Paracetemol. Both are used for pain, headaches, etc. I will make an appointment with a physiotherapist for sure on Monday. Like you said even one time may be enough, just to find out if I should rest or exercise my arm and shoulder. I cannot take anti-inflammatories, they make my stomach bleed. Thanks again for your help.
